Product DescriptionThe Bravo Company BCM MCMR-8 is a lightweight, M-LOK compatible modular rail handguard built around BCM's proven barrel nut and lock-up design first introduced with the KMR series. Precision machined from aerospace-grade 6061-T6 aluminum, this free-float handguard delivers excellent strength-to-weight with a slim, proprietary profile for added cross-sectional rigidity. A patented mounting system (US Patent 8904691) provides a mechanical index to the 12 o'clock rail and positions mounting hardware to help mitigate shift from heat generated during firing. Designed for AR-15 platforms in 5.56, the MCMR-8 is optimized for pistol-length or carbine-length gas systems when used with a low-profile gas block, and includes the steel barrel nut plus factory hardware and tools for installation.Product Highlights M-LOK compatible modular mounting surface for lights, grips, and other accessories Free-float handguard design helps reduce barrel deflection for consistent accuracy potential Precision-machined 6061-T6 aluminum construction for high strength with low weight Steel barrel nut and BCM lock-up system designed to resist movement under heat Slim profile with approx. 1.3 in inside diameter and 1.5 in overall width for a comfortable gripSpecs Brand: Bravo Company Model/Series: BCM MCMR-8 (MCMR) Product Type: Free-float handguard / rail Mounting Interface: M-LOK compatible Compatibility: AR-15 (5.56) Color: Black Material: 6061-T6 aluminum (handguard); steel (barrel nut) Finish: Hardcoat anodized (MIL-A-8625F Type III) Length: 8 in class; actual length to flare: 8.14 in Inside Diameter: 1.3 in Overall Width: 1.5 in Weight: 7.6 oz total (handguard 5.3 oz; hardware 2.3 oz) Included: Steel barrel nut, factory hardware and tools UPC: 812526021663 Manufacturer Part Number: BCM-MCMR-8-556-BLKDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
